STAPLE-SETTING DEVICE.

7 Application filed July 2,

To all whom it may concern: Be it known that I, KIT C. Crnmrnninnrn, a citizen of'the United States of America, residing atHouston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Staple- Setting Devices, of'which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to blind staple setting devices and has for an object to provide an improved device for setting staples in blind slats and sticks, having special referonce to the setting of such staples for repair purposes, but providing also a means for the initial setting of staples.

A further object of the invention is to provide a device which can be associated with a blind which comprises the usual and ordinary pivoted slats and stick for setting staples in the edge of the slats and connected staples in the stick after first setting the staple in the slat.

With these and other objects in view the invention comprises certain novel units, ele ments, parts, combinations and mechanical movements as disclosed in the drawings, together with equivalents thereof as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a view of the device in top plan showing in dotted line the position of a blind slat and stick with the staple inserted in the slat;

Figure 2 is a view, partly in elevation and partly in section, of the device showing a similar positioning of blind slat and stick;

Figure 3 is an inverted fragmentary plan view, and

Figure 4 is a transverse sectional view taken on line H of Figure 2.

Like characters of reference indicate corresponding parts throughout the several views.

It is well known that in the setting of staples in slatted blinds, especially where the work is to be done after a blind is completed, as for instance for repair work, great difliculty is experienced by reason of the close proximity of the several parts.

The present invention comprises a plate 10 having a slide 11 mounted thereon in any approved manner, as by having flanges 12 Specification of Letters Patent. Patgnted F b 21,, 1922 1921. Serial No. 482,209. v

turnedfdownwardly overand sliding along the marginal edges of the plate '10, The plate is bifurcated at indicated in dotted lines at 14 and the members upon opposite sides of the bifurcations are turned up at 15 and provided with threaded perforations to'receive screws 16. The screws 16 bear andexert stress upon the slide 11 and are provided with collars 17 engaging inturned ends 18 of said slide 11. The screws are also preferably provided with winged extremities 19 by Whlch they may be manually actuated.

In alignment with the bifurcation 13 an arm 20 is provided, secured in any approved manner, as by being riveted, as indicated at 21. The arm 20 is turned upwardly at 22 with the extremity turned back upon itself at 23 to form one jaw of a clamp, the other jaw of which, 24, is pivoted at 25 and actuated by means of a knurled screw 26. The clamp jaw 24 is preferably provided with flanges '27 to properly position it relative to the arm 20, whereby it may be actuated through the medium of the screw 26 to clamp the staple 28.

In operation a staple is clamped in the clamp as indicated at Figures 1 and 2 to occupy the position shown therein. The device is now inserted between the slats of a blind with the slat occupying the position indicated at 29 and the stick at 14. The points of the staple are, of course, at this particular stage of the proceeding not inserted in the edge of the blind as indicated in Figures 1 and 2 but the insertion is accomplished by manipulating the screws 16, drawing the entire device relative to the slat until the staple has been inserted into the slat to the depth as indicated. By loosening the staple clamp and reversing the action of the screws 16 the device may be removed from its relation with the slat and stick.

It will be apparent that the staple is now insertedin the slat on the edge opposite the stick and that it is necessary to reverse this position and attach it to the stick. The reversal will be done by simply swinging the slat upon its pivot. This accomplished, the slats are moved as nearly as may be to completely closed position, whereupon the device with another staple in its clamp is turned on edge, the staple hooked through the staple already set in the edge of the 13 to receivethe stick slat, and by moving the slide 11 to the proper position the stick may be engaged by such slide and the staple forced into the stick while still hooked in the staple Previously set in the edge of the slat.

What I claim is: V

1. A staple setting device comprising a bifurcated plate, a slide slidable upon the plate, screws upon opposite sides of "the engagement with the slide adjacent its opposite ends.

3. A staple setting device comprising a plate having a slit in one side forming a bifurcation, a staple clamp at the opposite side of the plate in alinement with the bifurcation, a slide mounted upon the plate having extremities turned as flanges about the edges of the plate and having a working face normally'perpendicular to the bifurcation, and screws carried by the plate upon opposite sides of the bifurcation bearing against the slide adjacent its opposite ends. In testimony whereof I hereunto affix my signature in presence of two Witnesses.
